LU multiple-aspect signalling

So, following your rules as posted, a 165 approaching Moor Park NB with
a Met in front would see this:
[...]
Note that a green 3-aspect signal (A860) can be followed by a double
yellow 4 aspect signal OR a single yellow 4 aspect signal (A864) - if
I've read your post correctly, on NR this is a Very Bad Thing.
Correct; NR rules don't allow this (on continuously signalled routes; it
is allowed on an intermittently signalled route).
Unless A860 is held to yellow if A864 is single yellow? Or have I
managed to misunderstand?
No, it sounds like you've got it exactly.
But, as I said, LU does it differently.
